A new study published in Science brings scientists one step closer to developing a lithium-air battery, which could someday be lighter and last longer than the lithium-ion batteries currently found in cell phones, laptops, and hybrid cars.
Lithium-air batteries are a hot area of investigation—a handful of research institutions and companies are currently exploring the technology for use in vehicles. However, the technology is in its infancy and many challenges to a practical rechargeable lithium-air battery remain.
DILLINGHAM, Alaska—Tom Marsik and Kristin Donaldson are building a house a few minutes’ drive from the center of this small city, a two-story model with peat-brown vinyl siding that blends easily with the yellows and golds of the tundra in early autumn. The location is stunning, but it’s only from the inside that you see the building’s defining characteristic: White-painted walls that are more than two feet thick.
